The writer wants to organize the sentences below to logically present the chronological steps and historical significance of the accidental discovery of YInMn Blue. What is the most logical order for these sentences?
- 1In 2009, chemist Mas Subramanian and his team at Oregon State University were attempting to synthesize new materials for electronics by heating manganese oxide along with other chemical compounds to high temperatures.
- 2To their surprise, rather than yielding a material with useful electrical properties, the intense heat transformed the mixture into a brilliant, durable blue compound.
- 3Subramanian immediately realized that this vibrant color was unique, as the crystal structure of the new material prevented it from fading even when exposed to water or acid.
- 4This accidental creation, later named 'YInMn Blue' after its constituent elements, marked the first discovery of a new blue pigment in over two centuries.
Answer
The correct sequence begins with the introduction of the 2009 experiment, followed by the description of the heat reaction, then the realization of the pigment's durability, and concludes with its naming and historical significance.
The correct order follows a clear chronological and logical progression. It starts by introducing the initial experiment in 2009, followed by the immediate reaction to the heating process, then details the physical properties observed by the chemist, and concludes with the naming and historical impact of the pigment.
